Internship Ruby Rails Developer Jobs in Manhattan, NY

Rhino + Jetty is making housing more affordable and accessible for millions of renters each year. We're the market-leading rental housing platform building simpler, more accessible ways for people to move into homes — and for property managers to lease with confidence.

Our technology removes friction from the move-in process, lowers upfront costs for renters, and helps property managers make faster, more accurate decisions. We support a network of 3 million rental units nationwide and work with 47 of the NMHC Top 100 property owners, including Greystar, Brookfield, Asset Living, UDR, and more.

We pioneered security deposit insurance and continue to push the industry forward with a growing suite of products — from deposit management to lease guarantees and loss-of-employment protection. We're growing quickly, tackling real problems at scale, and building technology that's changing how renting works.

In this role, you will:

• Design technical solutions that are reliable, fault-tolerant, scalable, and performant
• Write code (often with AI assistance) to produce quality, readable, testable, maintainable software
• Participate in code reviews and design sessions
• Launch new features and services to our customers with high quality customer experiences
• Work with product managers and your engineering team to size work and understand build options
• Foster a culture of security and will adopt security best practices throughout Rhino+Jetty’s codebase

Our current technical stack most prominently features:

• Ruby (Rails), Python (Flask), Javascript (Hotwire, React.js, Next.js)
• Postgres
• AWS infrastructure managed via Terraform 
• Datadog, Posthog, Rollbar, Sentry
• Claude AI tools (Chat, Cowork, Code)
• IDE(s) of choice

The candidates we’re looking for generally have most of the following:

• 5-10 years of experience in building production-grade, high-volume software systems
• Professional coding experience (e.g. Ruby on Rails, Python, Javascript, React) with the willingness to recommend and adopt new technologies as necessary
• Full-stack experience or willingness and ability to learn across the stack
• Experience working with AI tools to accelerate your engineering work (e.g. Claude Code, ChatGPT Codex)
• Experience with server-side concepts (microservices, caching, performance, monitoring and scalability)
• Experience with modern databases (e.g. Postgres) and appropriate application-side data modeling
• Experience with modern source control tools (git + GitHub)
• Understanding of CI/CD build/deployment tools (e.g. GitHub Actions; Semaphore)
• Familiarity with AWS cloud technologies (e.g. ECS, S3, RDS, etc)
• Willingness to become domain subject matter experts in a highly regulated industry
• Enthusiasm, curiosity, and the flexibility to thrive in a start-up atmosphere of constant change and growth 
• Ability to use AI tools and your own creativity to tackle new challenges

These aren’t required but are a big plus:

• Experience working in Fintech, Insurance, Banking or other similar financial services
• Prior professional experience in Ruby / Ruby on Rails
• Exposure to data pipeline tooling (e.g. Fivetran, dbt)
• Early/mid-stage startup experience
